Be it known that I, AfUeUsTUs T1-rum, of Albany, in the conn-ty of Albany, and State of ANew York, have invented anew and improved Combination of a Screen and Scoop; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. I

lThis invention consists'in a new and improved combination of a screen and scoop, asrhereinafterfully shown and described, whereby a` scoop orsmall shovel may, with the greatest facility, be converted into a screen whenever desired. v y 1 The invention is applicable to nre-shovels, and may bel applied to scoops of all kinds.-

In the accompanying sheet of drawingsl Figure l'is a plan or top view of my invention.'

Figure 2, a transverse vertical section of the same, taken in the line a: al', fig. 1.

vSimilar lettersof reference indicate corresponding parts.

lThe scoop may be conxitructed of sheet metal, ordinary'tinncd plate, orgalvanizediron plate,',according to the use for whichv the implement is designed. It is constructed with a back, a, and two sides, b b, the back having a' handle, e, attached, of any suitable length.

The device has no permanent bottom, bu`tat the inner surface lof the lower partof ech side I there are two parallel'grooves, d d, placed one above the other, as shown` clearly in fig.p2, a slide, being fitted in the lower grooves, and a screen, B, i-n the upper grooves, or. vice versa.'

The front or outer end of thescoop is provided with a flap or door, C, whichis connected at its lower end, by a hinge or any suitable joint, tothe scoop, and a spiral or other suitable spring, e, is applied to the Bap' or door, which spring, by a slight shake-motion of the scoop, has o. tendency to throw, the ilap or`door up, and keep the end of the scoop closed, said iap or door opening inward or backward by a very slight-pressure, the door-when elevatedand closed, bearing against stop'sf, at the inner surfaces of the sides b b.

When the device is used 'as a scoop, the screen B may bewithdrawn, and whenused -as a screen -the slide A is withdrawn. I v

In shoving thc front end of the device int'o the article to be lifted andscreencd, the flap or door C will be Lforced back, and the screen will be filled, and,bya' slight shake of'the device, the iap or door will be raised by the. springe, an'd the substance may then be screened by shaking the device.

l When the substance is fully screened, the ne portion having pn'ssed tbroughthe screen, the eonrser par-4 ticles left on the top, may be discharged by-shoving back thc ilap'or door, or by 4simply inverting the implement. This device may he very cheaply constructed, and used'for iireshovels, for siftingcinders from shovels, and also for scoops generally..

Different-sized screens may be used, according to the character or nature of the materialito be screened. I claim a's no\v,land desire to secure by Letters Patentml A 1.
